使用JSON.stringify()时,json2.js似乎忽略了父对象的成员.例:

require('./json2.js');

function WorldObject(type) {    
    this.position = 4;
}

function Actor(val) {
    this.someVal = 50;
}

Actor.prototype = new WorldObject();

var a = new Actor(2);

console.log(a.position);
console.log(JSON.stringify(a));

输出是:

4
{"someVal":50}

我希望这个输出:

4
{"position":0, "someVal":50}

我正在尝试为我的范围变量之一编写规范，但即使它们匹配，它也失败了。

安慰：
